Controlled Interventions to Reduce Burnout in Physicians

<jats:sec id="ab-ioi160098-4"><jats:title>Importance</jats:title><jats:p>Burnout is prevalent in physicians and can have a negative influence on performance, career continuation, and patient care. Existing evidence does not allow clear recommendations for the management of burnout in physicians.</jats:p></jats:sec><jats:sec id="ab-ioi160098-5"><jats:title>Objective</jats:title><jats:p>To evaluate the effectiveness of interventions to reduce burnout in physicians and whether different types of interventions (physician-directed or organization-directed interventions), physician characteristics (length of experience), and health care setting characteristics (primary or secondary care) were associated with improved effects.</jats:p></jats:sec><jats:sec id="ab-ioi160098-6"><jats:title>Data Sources</jats:title><jats:p>MEDLINE, Embase, PsycINFO, CINAHL, and Cochrane Register of Controlled Trials were searched from inception to May 31, 2016. The reference lists of eligible studies and other relevant systematic reviews were hand searched.</jats:p></jats:sec><jats:sec id="ab-ioi160098-7"><jats:title>Study Selection</jats:title><jats:p>Randomized clinical trials and controlled before-after studies of interventions targeting burnout in physicians.</jats:p></jats:sec><jats:sec id="ab-ioi160098-8"><jats:title>Data Extraction and Synthesis</jats:title><jats:p>Two independent reviewers extracted data and assessed the risk of bias. The main meta-analysis was followed by a number of prespecified subgroup and sensitivity analyses. All analyses were performed using random-effects models and heterogeneity was quantified.</jats:p></jats:sec><jats:sec id="ab-ioi160098-9"><jats:title>Main Outcomes and Measures</jats:title><jats:p>The core outcome was burnout scores focused on emotional exhaustion, reported as standardized mean differences and their 95% confidence intervals.</jats:p></jats:sec><jats:sec id="ab-ioi160098-10"><jats:title>Results</jats:title><jats:p>Twenty independent comparisons from 19 studies were included in the meta-analysis (n = 1550 physicians; mean [SD] age, 40.3 [9.5] years; 49% male). Interventions were associated with small significant reductions in burnout (standardized mean difference [SMD] = −0.29; 95% CI, −0.42 to −0.16; equal to a drop of 3 points on the emotional exhaustion domain of the Maslach Burnout Inventory above change in the controls). Subgroup analyses suggested significantly improved effects for organization-directed interventions (SMD = −0.45; 95% CI, −0.62 to −0.28) compared with physician-directed interventions (SMD = −0.18; 95% CI, −0.32 to −0.03). Interventions delivered in experienced physicians and in primary care were associated with higher effects compared with interventions delivered in inexperienced physicians and in secondary care, but these differences were not significant. The results were not influenced by the risk of bias ratings.</jats:p></jats:sec><jats:sec id="ab-ioi160098-11"><jats:title>Conclusions and Relevance</jats:title><jats:p>Evidence from this meta-analysis suggests that recent intervention programs for burnout in physicians were associated with small benefits that may be boosted by adoption of organization-directed approaches. This finding provides support for the view that burnout is a problem of the whole health care organization, rather than individuals.</jats:p></jats:sec>
